Referring to the drawings in detail a bending machine, in accordancewith this invention, includes a suspension element or structure,referred to generally by the ref-. erence character 8 and consisting ofa longitudinally disposed body portion 9 of appropriate length, heightand thickness, and whlch has its rear end downturned as at 10 andmerging into a yoke-shaped hanger 11 havlng the arms thereof indicatedat 12, 13'. Each arm is formed with an opening 14 through which extendsa gudgeon 15, carried by a plate 16 positioned against the outer face ofthe arm and secured therewith by holdfast devices 17. The outer face ofeach of the arms of the yoke 11 is formed with a vertically disposed,fiat rectangular offset or enlargement 17 having apertures 18. Extendingfrom each enlargement 17 to the body portion 9 is a reinforcing web 19.The body portion 9, intermediate its ends is formed with an upstandingarm 20 having the upper end thereof bifurcated, as at 21 and providedwith aligning openings 22. The base of the bifurcation at the upper endof'the arm 20 is indicated at 23 and is of arcuate contour. Dependingfrom the body portion 9, at a point between the arm 20 and the yoke 11',is a curved extension 24 which terminates in a yoke 25 provided with apair of arms 26, 27 and each of which is formed with an opening 28 forthe passage of a gudgeon carried by a plate 29, the latter being securedto itsassociated arm by holdfast devices 30. The outer faces of the arms26, 27 are reinforced by webs 31, which ex- .tend to and upon theextension 24:. The body portion 9 between the arm 20 and the forward endthereof is formed with an opening or passage32 which extends from thetopto the bottom thereof and is provided with inclined walls .33, 34, theformer extending at a greater'inclination than the latter and which isthe rear wall of the opening. The body portion 9 in proximity to the topthereof is formed with a pair of openings 35 arranged in proximity tothe walls 34 and which communicate with the opening or passage 32. p

The suspension element 8 is supported at it front and at its rear bystandards and the standards employed at the front thereofare indicatedat 36, and those at the rear at 37. The standards 36' are connected attheir upper ends by holdfast devices 38 to the forward end of the bodyportion '9 and the standards 37 are connected at their upper ends withthe element 8, by holdtast devices 39 which extend to the enlargements17 formed on the arms 12 and 13.

The gudgeons secured to the arms 12, 13 ot the yoke 11 are provided forsuspending a fluid pressure actuating device 40 for a piston rod 41 thelatter projects upwardly from the device 40 and said device is vertirally disposed. The arms 26, 27 of the yoke 24 overlap a fluid pressureactuating device 41 for a piston rod 42. The gudgeon's carried by thearms 26, 2'? support the fluid pressure actuating device 41, at anincline. tion and below the device 40. The devic 41 arranged forwardlywith respect to the lower portion of the device 40 and de pends at adownward inclination h'lounted in the bifurcated upper end of the arm520 at a point between its vertical median and its forward end is alever arm 43, which is pivot-ally connected to the arm 20. as at 44. Thelever arm 43 projects slightly forward ot the arm 20. The rear end ofthe lever 43 is pivotally connected as at 45 to the upper end of thepiston rod 41. The forward end the lever arm 45:3 has pivotallyconnected therewith, as at 46 a depending combined holder and presserhead "or element 47. Pivotally coni'iected to the outer end of thepiston42, as at '48, is an upstanding lever arm 49, which extendsthrough the opening 32 and is pivoted with the bodyportion 9 as at 50.The pivot '50 is arranged between the transverse median and upper end ofthe arm 49 and further at 'a point between its longitudinal median andits forward edge. The pivot 50 is eccentrically disposed with respect tothe opening 32, that is to say it is 'arranged at a point between thevertical median and the forward wall of the opening 32 "and furthershove the longitudinal center 01 the body portion 9. The lever arm 49extends a short distance above the body portion 9 and that part of theforward edge of said arm 49, above and helow the ivot 50 inclinesrearwardly throughout. Tie upper ehd of the lever arm 49 carries a pivot'53 which projects from each side face thereof and conneete dto the'projecting ends of the pivot 53 are links 54 having their rear endspivotally connected at 55, to an upsetting head or element "56, which isi'rormally arranged helow the element 47 and slides upon the upper faceof the body portion 9 forwardly with respeet to the arm 20. When activethe element 56 moves towards the arm 20 and. the element 47 movestowards that partof the hotly portion'9 which is arranged forwardly ofthe arm 20. That part of the body portion between the arm 20 and therear wall or the openihg 32 provides a seat or anvil-57 for the band orclip '58 when the latter is mounted on the spring 59, see Figure 7.

The head or element 47 compresses the pose of shifting the elements 47and 56 hand 58 for the purpose of secr'u'in g it sides oi the clip orhand against the spring 59 and the element or head 56 upsets the freeends of the band or clip and further compresses the inner end of theclip or band when it is in the position shown in Figure 7.

The devices 40, 41 are provided for rocking the lever arms on theirpivots for the puror to the spring 59 to tightly bind the leaves orlaminations of the spring together. Any suitable means employed forcontrollingi the supply or fluid pressure to the devices 40 and 431.Eret'erahly the hand is forged to the spring. It will. he understood, ofc'oiirse, that any suitable clamping means may be employed to hold theleaves or laminatiohs of the springs together pending the closing of theclip or band or pending, the upsetting or forging ofthe clip or band inposition to tightly bind the leaves or laminations "oi the springtogether. The spring with the clip or hand is positioned on the part 57of the suspension elen'ieiit 8, and then the de vices 40 and 41 arethrown into operation which provide for the elements 47 and 56 to engagethe hand to secure it in position on the spring and after such actionhas taken place the elements 40 and 41 are coiitrollod in a manner torelease the lever arms 48 and 49 so that they will assume their normalpositions as shown in Figure 1. when the devices 40 and 41' are operatedthe piston 41 is moved upwardly and the piston 42 forwardly and when thepiston 41 moves upwardly the lever arm 43 is carried therewith, thattherear end thereoit, which lowers the forward end of the lever carryingthe element 4? therewith, hen the piston rod moves'torwardly the leverarm 49 is rocked on its pivot. in a direction whereby the lower end ofthe arm 49 will move forwardly, which swings the upper end of the armrearwardly and causes the element 56 to shift to active position.

It is thought the many advantages of a banding machine, in accordancewiththis invention can be readily understood, and although the preferredembodiment of the invention is as illustrated and described, yet it isto he understood that changes in the details of construction can he hadwhich will fall within the scope or the invention as claimed.
